Hydrophilic Polycarbonate Membrane Filter

Standard, PVP-treated, polycarbonate track etch (PCTE) membrane filters are our lowest non-specific binding membranes; hydrophilic, exceptionally strong, and extractable-minimizing properties make them ideal for blood assays, high-purity, and general filtration. 

Our hydrophilic PCTE membranes are produced from a a two-step, quality-assured, proprietary manufacturing process delivering consistent products with pore uniformity, predictable flow rates, and trusted particle retention levels. A single, integral, microporous polycarbonate film is used to produce the membranes and provide them with their thin, translucent, structure and the glass-like surface characteristics that enable superior particle visibility and easy microscopic analysis. These PCTE membranes are coated with polyvinylpyrrolidone to enhance the filter's ability process aqueous and alcoholic samples*. Their pores are absolutely-rated, precisely cylindrical, and narrowly distributed, allowing their surfaces to capture 100% of particles larger than pore sizes.

*The PCTE should not be allowed to dry after being wet, or it may lose its hydrophilicity.
